The appropriate temperature is the key to improving the survival rate of chicks. Because the newly hatched chicks are small in size, thin in villus and poor in body temperature regulation, they are sensitive to changes in the ambient temperature, and the chicks can maintain their body temperature relatively constant only at certain ambient temperatures. When the temperature of the environment changes, the physiological functions of the chicks will change. When the temperature exceeds a certain limit, it will cause metabolic disorders, immune suppression, and even death. Therefore, to improve the survival rate of broiler chickens, we must grasp and timely adjust the suitable temperature for brooding.
The most important point is to learn to "see chicken Schwen." Such as chickens gathered into a heap, indicating that the temperature is low, need to warm; chicks away from heat when drinking water, mouth breathing, indicating that the temperature is high, should be cooling; uniform distribution, sounds cheerful, indicating that the temperature is appropriate.
In addition, during the period of vaccination and vaccine response or when severe stress factors are encountered, the temperature may be temporarily increased by 1-2°C.
In short, if the temperature of the broiler is appropriate, it is necessary to refer to the thermometer, and it is even more necessary to “see the chicken to apply the temperatureâ€, that is, to timely adjust the brooding temperature by observing the broiler's mental status, behavior, and activity patterns. The principle is: early should be high, late should be low; small groups should be high, large groups should be low; weak young should be high, strong young should be low; night should be high, during the day, at noon should be low; windy and rainy days should be high, sunny low.
